attr:config is one of the ibs control msrs comparable with perfctr's
evntsel msr:
MSRC001_1030 IBS Fetch Control Register (IbsFetchCtl)
MSRC001_1033 IBS Execution Control Register (IbsOpCtl)
There are some options (randomisation, cycle/micro-op counting) but
usually it is null since the period is encoded in attr:period. But ibs
could be setup by an application using attr:config only which then
passes the value directly to the ctl msr.
